SAD-IRON.

Specification of Letters Patent.

Application filed April 13, 1911.

atented Sept. 23, 191.3.

Serial No. 620,953.

To all whom it may concern:

Be it known that we, JOSEPH F. LAMB and JOSEPH F. SMART, citizens of theUnited States, and residents of New Britain, in the county of Hartford,State of Connecticut, have invented certain new and useful Improvementsin Sad-Irons.

Our invention relates particularly to irons of the class havingremovable handles and consists of a novel form of handle and attachingmeans therefor.

In the drawings-Figure 1 is a side elevation of a sad iron made inaccordance with our invention showing in full lines the position of thehandle as it is applied to the iron and in dotted. lines the position ofthe handle after it is locked in place. Fig. 2 is a central longitudinalsection of the handle. Fig. 3 is a detail View, on enlarged scale, ofone of the studs.

Referring to the drawings thenurneral 1 denotes the iron, 2, 2 studssecured in the top thereof having tapering heads 3, 3, the undersides ofwhich are downwardly inclined as indicated at 4, 4: and illustratedclearly in the enlarged view of Fig. 3.

10 is the handle comprising a grip 11 and a base 12. The latter isapertured as at 13, 13 to receive the heads of the studs, ledges 14:, 14being formed at one side of said apertures which are adapted to underlieand interlock with the stud heads.

The base 12 is held up away from the iron by lugs 15 formed at theapertures 13, 13 opposite the ledges 1 1, 1 1 and by the lugs 16, 16formed at intervals along the edges of the base, providing for the freecirculation of air and also properly positioning the ledges 141, 1 1with respect to the stud heads; the lugs 15 being at the opposite sidesof the apertures from the ledges 1 1, 14 perform the further function ofpreventing engagement of the base with the stud heads when the handle isbeing removed and also prevent sidewise movement of the handle on thebase owing to the fact that they extend around on the sides of the studsas clearly seen in Fig. 1.

The means provided for shifting the handle longitudinally on the iron tocause the ledges 14, 14 to in erlock with the stud heads, and to hold itin this position, con sists of a lever 20 pivoted on a convenient partof the handle, as one of the base uprights 21, and having an aperture 22which is above one of the apertures 13 in the base but slightly out ofalinement therewith.

The aperture in the lever is at a greater distance from the fulcrum thanthe aperture in the handle, and in consequence when the handle isapplied to the iron, the lever is held raised owing to the engagement ofone wall of the aperture with the tapered head of one of the studs. Ifnow, the handle is released the weight of the lever causes it to drop,the tapered head of the stud exerting a camming action on the lever soas to shift the whole handle laterally carrying the ledges 14, 141 underthe stud heads. Both ends of the handle base are thus interlocked withthe studs which are arranged near the ends of the iron and the handlecannot be disengaged from the iron without manually lifting the leverand shifting the whole handle so as to disengage the ledges from thestud heads.

The utility of the inclined undcrsides of the stud heads now becomesapparent. As the handle shifts longitudinally due to the (ramming actionof one of the studs on the lever, the ledges are drawn under the studheads and ride down the downwardly inelined surfaces which act to wedgethe base firmly down onto the iron. In case of wear, or if it desired tomore firmly attach the handle to the iron, the lever can be pressed downmanually which causes a still further longitudinal movement of thehandle and a stronger wedging action tending to clamp the handle ontothe iron.

By preference the handle base is made up out of sheet metal stamped toshape and suitably stiffened, the lugs being formed by drawing down themetal at the edges of the base and also by drawing down the metal arounda portion of the wall of the apertures, the ears between which the leveris pivoted. being folded over from one of the handle uprights. The leveralso formed up from sheet metal and preferably the walls of its apertureare drawn down to form a bearing surface of some considerable extent.

It is, of course, clear that the handle is reversible and for thisreason we prefer to make the studs of cylindrical shape. It will also benoted that in applying the handle to the iron it is not necessary totouch ill i an iron, a palr ,of studs mounted. n the top thereof, vahandle llaVlHg. a base apertured of modifications and we desire to coverby' the appended claims any and all such modifications as come withinthe spirit of the in- 1 vention.

We claim as our invention:

1. In an article of thecharacter described, an iron provided with a studin the top thereof, a handle having a base apertured to receive saidstud, and a gravity-operated device fulcrumed on said handle andconstituting in cooperation with the head ofsaid stud a common means forfirst engaging said handle with said stud, and next for locking theparts in engaging position.

2. In an article of the character ,described,

.to receive said studs, interengaging parts on the handle-base. andstuds, and a gravity- ,operated device fulcrumed onsaid handle andconstituting in cooperation with the head of one of said studs a,co1nmonmeans for first engaging said handle with said studs, and then forlocking the parts in engaging position. i

3. Inan article of the character described,

an iron, a stud mounted thereon, a handle including a base apertured to,receive said stud, and a gravity-operated lever. fulcrumed on thehandle, and having a face adapted to cooperate with said stud, theaperture in the base and the operative face ,of the lever. being atdifferent distances from the ful-' crum ,point of the lever whereby saidlever will first cause a 'longitudinal movement of the handle and itsbase to engage it with said stud and thenlock the parts againstaccidental disengagement.

4. In .n articlepf the character described, ,an iron, a stud mountedthereon, a handle comprising a base apertured, to receive said stud, anda gravity-operated lever fulcrumed upon the handle and apertured toreceive the stud, the aperture in the lever being at a-greater distancefrom the fulcrum point of the lever thanthe aperture in the base of the,handle.

5. v In an article of thecharacter described, an iron, a pair of studsmounted in the top thereof, a handle provided with a base apertured toreceive the studs and which isshiftable longitudinally to cause thehandle and studs to be engaged, and a gravity-operated lever fulcrumedon the handle and cooperatingwith one of said studs to first shift thehandle into engaging position with the studs, and. next to lock saidhandle in engag ng position.

6. In an article of the character described, an iron, a plurality ofheaded studs mounted in the top thereof, said studs being transverselygrooved, the upper walls of said grooves being downwardly vinclinedtoward the center of the studs, a handle including a base, means forspacing saidhandle base from the top of said iron-to. bring it'inalinement with the grooves in the studs, a gravity -.operated leverfulcrumed on the handle andadapted to cooperate with one of said studsand constituting a common means to shift said handle and baselongitudinally to engage itwithsaid studs, and then to lock said partsin engaging position, said lever being manually operable to produce afurther longitudinal movementof said handle and't-o cause the inclinedwalls cally arranged at the top thereof, a handile comprising abase anda' grip; attached thereto, said base-having apertures to receive saidstuds, ledges atcorresponding sides of said apertures adapted tointerlock with the=heads of said studs, walls 7 of substantial depthformed at said apertures opposite thesaid; ledges, a leverfulcrumedonsaidbase and having an aperture arranged above one of the apertures insaidbase, but slightly out ture in said lever being adapted-t0 cooperatewith the head of either one of said studs for the purposes set forth.
